The second form of solution of (REF ) is found using result
255.00 in [1]}. Its parametric form is
\( \left\lbrace  {\begin{array}{l}\varphi = \frac{\textstyle \varphi _3-\varphi _4 n \mathrm {sn}^2(w|m) }{\textstyle 1-n \mathrm {sn}^2(w|m)} ,\\\xi = \frac{\displaystyle 1}{\displaystyle \varepsilon p}(w\varphi _4-(\varphi _4-\varphi _3)\Pi (n;w|m)),\\\end{array}} \right.\)
